Analysis of the value of follicular helper T cell(Tfh) subsets in the diagnosis of active ulcerative colitis (UC). Programmed cell death protein 1 (PD‐1)⁺ Tfh cells, inducible co‐stimulator (ICOS)⁺ Tfh cells, ICOS⁺PD‐1⁺ Tfh cells in 68 cases of UC patients were analyzed, including 34 active UC patients and 34 cases of stable remission UC patients. The receiver operating characteristic (ROC) curves were performed to evaluate the efficacy of Tfh subsets (or joint use) for prediction of active UC patients (versus stable remission UC patients). Area under the curve (AUC) calculated for ICOS⁺PD‐1⁺ Tfh cells in combination with PD‐1⁺ Tfh cells (black line) and ICOS⁺PD‐1⁺ Tfh cells alone (red line) are listed.
